8 Claims.

This invention relates to winding machines in which the yarn package ismovable away from its rotating driver when its propulsion thereby is tocease, as when the winding is completed or the yarn breaks.

The invention contemplates means for causing movement of the packageaway from the driver which shall operate without straining or undulyrubbing the yarn and also so as to cause the taking up of any slack inthe yarn that usually develops on such movement between the package andthe revoluble swift or equivalent supply from which the yarn is drawn;which shall be adapted to be put into action by the growing wound masswhen the latter attains a predetermined diameter, that is, when apredetermined extent of yarn has been wound, and for that purpose bepossible of adjustment so that any predetermined diameter of thecompleted mass may be possible; and which shall be simple inconstruction, readily applicable to conventional and existing windingmachines without material change therein, and reliable and efficient inoperation.

In the drawings,

Fig. 1 is a sectional view of a winding machine of the class indicatedin a vertical plane at one side of one of its core structures andshowing the improved means in idle condition;

Fig. 2 is a similar view, showing said means in the condition it assumesfor holding said structure displaced from the driver;

Figs. 3 and 4 are, respectively, a plan and a front elevation of what isshown in Figs. 1 and 2 with said means in the position of Fig. 1 and thespool nearly filled; and

, form trunnions engaged in the slots of the guides oluble switch orequivalent supply (not shown) and suitably traversed, will be wound onthe spool portion of the core structure in layers extending from end toend thereof. The direction of rotation of the driver is as per the arrowin 5 Fig. 1.

Ordinarily, when the yarn being wound breaks or when the mass ofwindings appears to approximate some predetermined diameter theattendant grasps the package and deposits it, clear of the driver, withits spindle ends resting in sockets, as r, of the brackets. Theattendant may strain the yarn in so doing and usually the suddenstopping of the package produces slack between the latter and the yarnsupply; moreover the attendant cannot accurately gage just how muchextent of yarn is wound on the core structure, in consequence of whichin a run of the wound core structure some will carry appreciably moreand some appreciably less extent of yarn than intended. When the meansof this invention is incorporated in the machine the possible strainingof the yarn and its overrunning and the consequent slack therein and allappreciable friction thereon are avoided and a run of wound corestructures will be found to carry substantially the same extent of yarn.

Shifters in the form of cam devices, movable on the frame, are adaptedby acting upon the core structure to cam it away from and support itclear of the driver. In the example these are segment-shaped levers 9movable in planes crossing the axis of the core structure and eachhaving a peripheral cam portion 9a arranged on movement of the lever toengage the spindle of said structure to bring into effect their cammingaction. When the winding starts these shifters are in retracted position(that is, in the example the levers forming them are up, Fig. 1), sothat the portions 9a permit the core structure to rest 40 on and thus bedriven by the driver; but when rotation of the core structure shouldcease they are made to assume the position of Fig. 2, where they havecammed the core structure clear of Y the driver, guided by the slots ofthe guides 3. In the example, and preferably, the shifters are normallyurged, as here by gravity by weighting at 91) the levers forming them,to the position of Fig. 2, being releasably held in the position of Fig.1 as follows:

An elongated plate l0 has end trunnions Ina journaled in bearings 21:.in the brackets and by which it is pivotally suspended, its other orlower long edge engaging (Fig. 1) abutments 90 on the shifters whichface in the direction in which 55 the shifters tend to turn. The platethus forms a detent; and if this detent be moved clockwise the shifterswill be freed to move forward to assume the position of Fig. 2. Inasmuchas gravity tends to urge the plate to vertical position it acts to wit:The abutment of each shifter forms one side of a salient angle of an arm9d of the shifter, the other side being coactive cam-fashion with thelower edge, of the detent (plate 10). The

shifters being down movement of the detent counter-clockwise involvesthe camming of the shifters by the detent counter-clockwise, and thismay continue until the detent assumes obstructing relation to theshifters by coming into engagemerit with their abutments 9a. In short,the lower edge portion of the detent and the salient angular portion ofeach shifter form portions coactive with each other on the movement ofthe detent in one direction first to retract the shifter and thenobstruct its forward movement.

The detent has an arm (constituting a part of the lever formed thereby)consisting of a platespring H one end of which laps the face of thedetent opposite to that wiped by arm 9d and is held under lugs I bthereon and the other end portion of which is rebent to oppose said faceof the detent and then bent off so as to be opposite the barrel of thespool 8. The described manual resetting of the shifters at retractedposition, as well as the release thereof, may be effected manually bymeans of this arm as a handle. The arm also serves as a feeler ordetector to cause releasing movement of the detent when a predeterminedextent of yarn has been wound on the spool and it is adjustable for thispurpose as follows: Tapped into the detent is a screw I 2 which bearsupon the said rebent end portion of the spring II. By turning this screwand so shifting the arm relatively to the body or plate portion of thedetent the distane between the free or feeling end of the arm and thespool barrel in that position of the detent where it holds the shiftersretracted may be varied. When a predetermined extent of yarn has beenwound on the'spool according to the adjustment of the arm the wound massobviously trips the detent so that the shifters fall and displace andsupport the wound core structure clear of the driver.

The action of the shifters to displace and support the core structureclear of the driver is always assured by the traction, once established,between the rotating spindle and the cam surfaces 9a. And the minimum offriction between the narrow cam surfaces 9a and the core structure,taken with the fact that the shifters engage the slender trunnion partsof the core structure so that the momentum of the latter remains fullyeffective, permits the core structure to come gradually to a stop sothat any slack that might otherwise form between the core structure andthe yarn supply is taken up whenever the stopping occurs with the yarnintact.

Since the camming action is here directly applied to the core structure,that is, not to the yarn mass, and since the latch lever is verysensitive to movement by the wound mass to trip the shifters there is noundue rubbing of the yarn.

The shifters may be fulcrumed as shown in Fi where in an arm 2b of eachbracket is fast an internally threaded bushing l3 and the correspondingshifter has held therein by a screw 14 a threaded stud I 5 which istapped into and revolves freely in the bushing.

The latch plate is shown in two sections connected by a bolt l6penetrating a longitudinal slot I I in one section so that the plate maybe adjusted to suit different spacings of the brackets 2.

In these machines the driver frequently has only one wheel 5 and thecore structure only one whirl l to coact therewith, in which casestopping of rotation of the core structure is effected by tilting thelatter to clear the whirl from the driver. In the application of myinvention to such a case only the shifter for the whirl end of the corestructure need be present.

Having thus fully described my invention what I claim is:

1. In combination, with the frame, a rotating driver jo-urnaledtherein'on a substantially'horizontal axis, a revoluble core structurefor the yarn windings confined by the frame to movement toward and fromand normally held in peripheral contact with and thereby adapted to bedriven by the drive-r and having a relatively slender axial portion,and. a cam device movable in the frame against said axial portion to camthe core structure clear of the driver.
